Diaz is suspended until February due to a failed post-fight drug test following a loss to Carlos Condit. He announced his retirement after the match, but has said he wishes to return, fighting the suspension in court.

Koscheck was knocked out of a bout with Jake Ellenberger due to a training injury. “Kos” added that he’d “like to fight (before) Feb…..” but that the opportunity to meet Diaz might be too much to pass up.
